SHACKLE DEVICE Fil ed Aug. 9, 1952 INVENTOR Patented Oct. 23, 1934 UNITED STATES 1,977,852 .SHACKLE DEVICE Raymond W. Juengst,

My invention relates to a means for connecting the frame and spring of an automobile and more particularly to an improved connection involving a so-called anti-shimmy device.
It is the principal object of the invention to provide an anti-friction shackle device with antishimmy means which will be effective in use,
relatively cheap to manufacture, and not likely to get out of order.
hereinafter pointed out or will become apparent upon a reading of the specification.
In the drawing which shows, for illustrative purposes only, apreferred form of the inven- Fig. 1 is a fragmentary side view ofa frame and springv connected by my: improved shackle device and illustrating anti-shimmy mechanism;
Fig. 2 is a part sectional view taken substan 20 tially on the plane of the line 2-.-2 of Fig. 1;
Fig. 3 is an inside view in. elevation of one of the. shacklelinksshown in Figs. 1 and 2.
In said drawing 5 indicates part of a frame and, as illustrated, isthe front or horn end of a frame; The frame is provided with a downwardly extending rigid arm 6 comprising part of the anti-shimmy device to be later described. '7 indicates-part of a spring to be shackled to the frame. The frame'and spring are shackledvto each other through anti-friction bearing means, and in the form shown I provide a pair of shackle links 8.-9, each having raceways 1011 for antifriction bearing members 12-12. Coacting raceway means are carried by the frame and spring and in the form shown I employ shackle pins 13-14 rigidly secured respectively in eyes of the frame and spring. These shackle pins project beyond the sides of their supporting members and are provided with raceway means for coaction 40 with the anti-friction bearing members 12-12 whereby the frame and spring will be anti-frictionally supported from each other.
In the form shown, the shackle links are duplicates of each other and preferably comprise sheet ,;metal channel shaped members, that is, each link is preferably provided with an upstanding marginal flange 15 which may be continuous so as to provide a very light, yet exceedingly rigid, link. The links may be connected by means of a through bolt 16, and, if desired, spaced apart by a spacer 1'7 interposed between the two links. The anti-shimmy mechanism cooperates with the lower ends of the links.
In the form illustrated, the lower ends of the links are extended downwardly and are of re- Other objects and features of invention will be 1932, Serial No. 628,057
duced width, as shown particularly in Figs. 1 I
and 3. Abutment means in the form of a block 16 may be interposed between the links 8--9 and is preferably of a width to be received snugly between the fianges on each channel link so that the flanges'assist in supporting the abutment means against rotation. The block 16' may have; integral threaded lugs 1717'.extendingithrough holes such as 18 in eachv of the links, and nuts l9'-l9 serveto draw the links toward eachother and up against the block 16, or, as specifically shown, against the washers or integral lands 20 thereon.
In order to limit the shackling motion of the shackle, I providespring means. As illustrated, the block 16 may have a pair of holes 21 extend- 1 ing therethrough for the loose reception of a 1 pair of bolts such as 22. A pair of springs such as 23 may surround the bolts 22 and be inter-.
posed between the frame arm 6 and, the abutment block 16. The frame arm may berecessed. as indicated at 24, and the abutment block may be correspondingly recessed as indicated ,at 25 for the reception of the one or more anti-shimmy springs 23. a At the opposite side of the abutment block 16 there may be another pair of anti-shimmy springs such as 26 engaging the abutment. 16 in recesses such as 27 therein. Each bolt 22 may have an abutment collar 28 thereon adjustably, held by'a nut;29 for engagement with the opposite ends of the springs 26. Thus, by adjustment of the nut- 29, the effective functioning 'of the. springs 23-26 may be altered.
When the device is in use, the normal shackling action of the shackle is resisted in one direction by the springs 23 and in the opposite direction by the springs 26. It is to be noted that, as illustrated, the holes 21 are larger than the shanks of the bolts 22 so as to permit freedom of action during the shackling movement. Since the action of anti-shimmy devices is well known at this time, no particular description of the functioning thereof need be here recited.
While the invention has been described in considerable detail and a preferred form illustrated, it is to be understood that various changes and modifications may be made within the scope of the invention as defined in the appended claims.
